Government Lab Reveals Quantum Internet Operated for 2 Years


One of the dreams for security experts is the creation of a quantum Internet that allows perfectly secure communication based on the powerful laws of quantum mechanics.

The basic idea here is that the act of measuring a quantum object, such as a photon, always changes it. So any attempt to eavesdrop on a quantum message cannot fail to leave telltale signs of snooping that the receiver can detect. That allows anybody to send a “one-time pad” over a quantum network which can then be used for secure communication using conventional classical communication.

That sets things up nicely for perfectly secure messaging known as quantum cryptography and this is actually a fairly straightforward technique for any half decent quantum optics lab. Indeed, a company called ID Quantique sells an off-the-shelf system that has begun to attract banks and other organisations interested in perfect security.

These systems have an important limitation, however. The current generation of quantum cryptography systems are point-to-point connections over a single length of fibre, So they can send secure messages from A to B but cannot route this information onwards to C, D, E or F.

That’s because the act of routing a message means reading the part of it that indicates where it has to be routed. And this inevitably changes it, at least with conventional routers. This makes a quantum Internet impossible with today’s technology

Various teams are racing to develop quantum routers that will fix this problem by steering quantum messages without destroying them. We looked at one of the first last year. But the truth is that these devices are still some way from commercial reality.

Today, Richard Hughes and his team at Los Alamos National Labs in New Mexico reveal an alternative quantum Internet, which they say they’ve been running for two and half years. Their approach is to create a quantum network based around a hub and spoke-type network. All messages get routed from any point in the network to another via this central hub.

This is not the first time this kind of approach has been tried. The idea is that messages to the hub rely on the usual level of quantum security. However, once at the hub, they are converted to conventional classical bits and then reconverted into quantum bits to be sent on the second leg of their journey.

So as long as the hub is secure, then the network should also be secure.

The problem with this approach is scalability. As the number of links to the hub increases, it becomes increasingly difficult to handle all the possible connections that can be made between one point in the network and another.

Hughes and co say they’ve solved this with their unique approach which equips each node in the network with quantum transmitters—ie lasers—but not with photon detectors which are expensive and bulky. Only the hub is capable of receiving a quantum message (although all nodes can send and receiving conventional messages in the normal way).

That may sound limiting but it still allows each node to send a one-time pad to the hub which it then uses to communicate securely over a classical link. The hub can then route this message to another node using another one time pad that it has set up with this second node. So the entire network is secure, provided that the central hub is also secure.

The big advantage of this system is that it makes the technology required at each node extremely simple—essentially little more than a laser. In fact, Los Alamos has already designed and built plug-and-play type modules that are about the size of a box of matches. “Our next-generation [module] will be an order of magnitude smaller in each linear dimension,” they say.

Their ultimate goal is to have one of these modules built in to almost any device connected to a fibre optic network, such as set top TV boxes, home computers and so on, to allow perfectly secure messaging.

Having run this system now for more than two years, Los Alamos are now highly confident in its efficacy.

Of course, the network can never be more secure than the hub at the middle of it and this is an important limitation of this approach. By contrast, a pure quantum Internet should allow perfectly secure communication from any point in the network to any other.

Another is that this approach will become obsolete as soon as quantum routers become commercially viable. So the question for any investors is whether they can get their money back in the time before then. The odds are that they won’t have to wait long to find out.

Grumpy Cat’s Worst Christmas Ever TV Movie Trailer

Grumpy Cat’s Worst Christmas Ever TV Movie Trailer

Grumpy Cat is of course the burned out Internet meme of a cat that always looks grumpy and cranky. Like all memes, it was entertaining for a whole fifteen seconds. But now the meme has been put to rest like all other stupid Internet fads. Or not! 

For some reason, executives at Lifetime thought it would be a good idea to make an actual made-for-TV movie starring Grump Cat. The only semi-redeeming factor is that Grumpy is voiced by Parks And Rec famous Aubrey Plaza. Only time will tell if that will be enough for the movie to not be completely awful.

Internet Throttling Is Evidence of Iranian Censorship


One of the growing concerns for human rights campaigners is the increasing evidence of Internet censorship in many repressive regimes around the world. During the Arab spring, for example, Egyptian leaders “switched off” the Internet in an attempt to prevent activists from organizing protests or communicating with the outside world. The Syrian leadership appears to have done a similar thing on several occasions during the current civil war.

But in Iran, the government is pioneering a more insidious — though equally powerful — form of censorship. Instead of shutting down Internet access, the government appears to be dramatically slowing its performance during periods of unrest. In February 2010, for example, the technology news website, The Next Web, recorded this effect in a story titled, “The Internet In Iran Is Crawling, Conveniently, Right Before Planned Protests.”

So-called “Internet throttling” has numerous advantages over a complete shutdown, since it constrains protests while allowing vital communications to continue. It is also difficult to distinguish from ordinary disruptions. The result is that throttling is much less likely to lead to widespread condemnation.

An interesting question is how to detect Internet throttling when it occurs. Today, Internet security expert Collin Anderson shows how publicly available data clearly reveals suspicious periods of Internet slowing in Iran and how this can be distinguished from ordinary slowing caused by high traffic, equipment failure and so on.

Although, as Anderson notes, Iran’s international gateways rank among the least stable on the Internet, it is important to recognize routing failures that are long lasting and widespread. Image courtesy of Collin Anderson.

The data that makes this possible comes from the Measurement Lab, a non-partisan organization that distributes open software for measuring Internet performance. M-Lab has developed a widely used network diagnostic tool that measures performance by sending a 10-second burst of data as fast as possible through a newly opened connection.

Since 2009, M-Lab has conducted some 200,000 connection tests per day, collecting over 700 Terabytes of data in the process. This is data from all over the world and is publicly available for anybody study.

Anderson’s analysis focuses on the data gathered from Iran since 2010. He says the results clearly show evidence of Internet slowing on several occasions. “We find two significant and extended periods of potential throttling within our data set, occurring Nov. 30, 2011 through Aug. 15, 2012 and Oct. 4 through Nov. 22, 2012,” he says. During the first of these periods, download throughput dropped by 77% and in the second it dropped by 69%.

Both of these occasions coincide with periods of unrest in Iran. During the winter of 2011, for example, two former presidential candidates were held under house arrest because of their reformist activities, triggering condemnation within Iran. In October 2012, there were widespread currency protests.

In addition, Anderson says there are another eight or nine shorter periods during which Internet performance slows suspiciously.

An important task is to distinguish periods of throttling from ordinary routing failures that are also common in Iran. To get an idea of the impact of an ordinary outage, Anderson studied the effects of an attack by the Kurdistan Workers Party on an international oil pipeline which also cut an important telecommunications link with Turkey.

He says this event caused a marginal increase in average and minimum round trip times for data as a result of data being routed over longer distances to M-Lab servers. However, the disruption was well below that experienced during other periods, a finding that gives weight to the notion that the internet in Iran is the subject of deliberate, centrally-controlled throttling.

Of course, more data is needed to reveal the nature of Iranian Internet throttling in greater detail, says Anderson. This may well be possible in the future given the increasingly widespread use of M-Lab’s diagnostic tools.

There is an urgent need for better monitoring elsewhere too. A growing body of anecdotal evidence indicates that other repressive regimes are beginning to copy Iran’s lead, with reports emerging of internet throttling in Bahrain, Syria, Tibet and Myanmar.

“For governments threatened by public expression, the throttling of Internet connectivity appears to be an increasingly preferred and less detectable method of stifling the free flow of information,” says Anderson.

His work and the brave contributions of his unnamed collaborators mark one small step in fighting back.

The Internet Has Found A Buddha Statue On Mars

In an attempt to make sense of what we perceive, humans always strive to find the familiar in the unfamiliar. The Martian landscape has been particularly subject to this train of thought lately. Some of the more eagle-eyed and imaginative among us have seen rats, a woman and, most recently, a floating spoon in images ofMars. Well, here is another one to join the Red Planet pareidolia files: a statue of a Buddha.

The image taken by NASAs Curiosity rover in 2014 was picked up by the YouTube channel Paranormal Crucible. In the video, they explain that the photo with colorization and a little artistic licenseshows therelic.

Alternatively, the vision in the rock could be explained bypareidolia, a phenomenon where humans spot significance in a vague stimulus, possiblydeveloped as an evolutionary advantage to spot predators before they saw us.

Mars is also subject to some pretty intense dust storms anddust devil whirlwindsthat could help explain the exotic and bizarre rock formation.
